Description Author  

This class can generate plasma style heatmap images from a set of points.

It takes the coordinates of a set of points and generates an heatmap image to overlay on top of another that represents the incidence of input points in each are by using hotter colors to denote areas with greater point incident.

The class generates the heatmap image and saves it to a file in JPEG format. It can be used to overlay on a page by using CSS opacity attributes to make visible any background graphics or page elements.
